Charging vs Temperature
The charging of Carefree batteries is best accomplished in a temperature
range of 60°F to 90°F. Charging within this temperature range requires
no temperature compensation. For applications over a wider temperature
range, charging voltage must be changed as a function of temperature.
(see chart at right)
Capacity vs Temperature
The efficiency of the lead-acid system decreases as the temperature
decreases and increases as temperature increases from room
temperature (70°) as illustrated. These four curves shown are based on
discharges at the 20 hour, 5 hour, 11/2 hour and 1 hour rates.
Self-Discharge Characteristics
High temperature increases the rate of self-discharge of all battery
systems but even in this respect, the lead-calcium battery is perhaps
least affected. In general, the rate of self-discharge can be expected to
double for each 20°F rise in temperature above 70°F.
Battery Operating Conditions & Cautions
Battery contains toxic material (lead) and corrosive fluid (sulfuric acid) •
Charging can produce explosive gases • Do not charge in gas tight
enclosures • Charge battery in a well-ventilated area away from sparks,
flames or smoking • Use approved voltage controlled charger • Do not
short-circuit battery terminals, as this can cause an explosion or fire •
Keep batteries and chargers away from children • Charge battery as soon
as possible after use • Do not store battery in discharged state • Do not
puncture, disassemble, mutilate or incinerate • MUST BE RECYCLED OR
DISPOSED OF PROPERLY
Installation Care
All CAREFREE batteries are carefully assembled and with proper charging
will provide excellent service. When placing the battery into service it must
be inspected to make sure that the battery has not been damaged by
rough handling. If the unit has been damaged, there is a possibility of a
loss of a small amount of sulfuric acid electrolyte and possible corrosion of
adjacent components. Any sulfuric acid can cause severe burns to the skin
and eyes. If contact is made with a damaged battery, immediately wash
the contacted area with water for at least 5 minutes. When installing the
battery in equipment, ventilation must be provided. Toward the end of
charge and under overcharge conditions, hydrogen and oxygen gas can be
generated. If this gas is allowed to accumulate in the enclosure and a
spark is introduced, an explosion could result.
